A reading list for debugging, .NET, CLR, WinDBG etc

I'm often asked "Where can I learn more about doing this kind of stuff?", this "stuff" being debugging with WinDBG, understanding how .NET works, looking at dump files and generally figuring out what's gone wrong with .NET applications.

I started assembling this list sometime ago and it is by no means complete. It keeps growing all the time (I have lists coming out of my ears. I squirrel away little nuggets of information, lists and lists of lists. Like any squirrel I spend half my time trying to find these little nuggets again :-).
